Application lled January 13, 1906. Serial No. 295,973.

T0 @ZZ whom it may concern: Be it known that I, GEORGE RoUNDs 5 HICKS, a citizen of the United States, residing i at Perrysville, in the county of Vermilion and State of Indiana, have invented a newl and useful Sawbuck, of which the following is a specification. A This invention relates to sawbucks, andi has for its object to provide improved means for retaining the log or other material in position on the sawbuc during the sawing operation without requiring the operator to hold his knee upon the log.

A further object of the invention is to provide a log-engaging member movable to operative position by a foot-operated lever or treadle, and, further, to provide an auxiliary lever for forcing said member into engagement with the work.

A still further object of the invention is to generally improve this class of devices so as to add to their utility and durability as Well as to reduce the cost of manufacture.

With these and other objects in view the invention consists in the construction and novel combination Aand arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of a sawbuck constructed in accordance with my invention and showing in dotted lines the initial position of the footlever and log-engaging member. Fig. 2 is a vertical sectional view-of the casing and locking-pawl. Fig. 3 is a side elevation of the foot-lever and a portion of the log-engaging hook. FigA is a side elevation of a sawbuck, illustrating a modified form of log-engaging hook. Fig. 5 is a transverse sectional view taken on the line 5 5 of Fig. 4. Fig. 6 is a detail perspective view of the pivoted end of the hook, showing the manner of mounting the spring.

Similar numerals of reference indicate corresponding parts in all the-figures of the drawm s.

The improved sawbuck consists of the supporting-brackets or cross-legs 5, provided tudinal rod 10,

with alined crotches 6, adapted to receive the logor other work 7 and'connected by a llongitudinal bar or brace 8, upon which is mounted for sliding movement an auxiliary `bracket or log-support 9.

Mounted for pivotal movement on a longiconnecting the lower ends of the cross-arms, is a foot-operated lever Aor treadle 11, said treadle being secured in position by suitable clips 12 and having its free end reduced and provided with a vertical lu 13, formed with a slot or recess 14. Secured to one longitudinal edge of the tread-le 11 is one end of a spring 15, the `opposite end yof which is fastened to the adjacent cross-leg '5, whileits intermediate portion is coiled around the rod 10 and serves to normally hold the free or reduced `end of the treadle in 'elevated position. The arm or extension 16 of "the spring is preferably held in contact with a laterally-extending pin 17 on the treadle by means of headed studs or pins 19, arranged one on each side of the pin 17, as shown. Pivoted at 2O in the slot 14 is the vcurved end'21 of a rack-bar 22, upon which is vslidably mounted for vertical inovementa casi 23, carrying a projection or lug 24 Aand -a pawl 25, the pawl 25 being held in yieldable -contact with the teeth on `the rack-'bar 'by means of a coiled spring 26, interposed between the handles 27. igidly secured yto the casing 23, as yby 'bolts or similar fastening 'devices28, is a log-engaging member 29, the free end 4of which terminates in a 4laterally-extending hook '30, adapted to impale the log or other work to be operated upon, as will be more fully explained hereinafter.

The treadle 11 nal slot or recess 31, and ydisposed within said slot and pivotally mountedon the pin 17 is a foot-operated 4lever 32, the long Iend rof which is provided with a vertical extension or lip 38, adapted to yengage and elevate the curved end of the rack-bar, while the opposite of short end of said lever extends above the general horizontal plane of the treadle and is formed with a terminal extension or lug 34, adapted to be depressed yby the heel of the operator.

In operation the log or other work to be operated upon is vseated in the orotches Aof the cross-legs, after which the 'log -iengagfing member is moved to operative position by depressing the treadle and said member adjusted vertically to accommodate the flog by is formed with `a longitudilOO releasing the pawl 25 and sliding the casing 23 on the rack-bar. The short end of the lever 32 is then depressed by the foot of the operator, which causes the long end thereof to elevate the curved end of the rack-bar and force the bill of the hook 39 into the log. When it is desired to release the log to permit the latter to be adjusted longitudinally within the crotches, the foot is removed from the treadle, the coiled spring serving to withdraw the hook from the log and return the treadle to elevated or inoperative position.

In Figs. 4 to 6, inclusive, of the drawings there is illustrated a modified form of the invention in which the foot-operated lever 32 is dispensed with, the log-engaging member 29 being formed of a continuous rod or bar, having an eye 35 in one end thereof and provided with a transversely-disposed pin 36. In this form of the device the free end of the treadle 11 is provided with a slot or recess 37 for the reception of terminal eye 35 of the member 29 .and through which passes a ivotpin or bolt 88, as shown. As a means for .yieldably supporting the free end of the rod 29 in engagement with the work when u the treadle is in elevated or inoperative position there is provided a suitable spring, preferably formed from single piece of springwire, an intermediate portion of which is bent to form a closed loop 39, which bears against the pivoted end of the rod 29 while its opposite ends are coiled around the transverse pin 36 at 40 and extended to form terminal spring-arms 4l for engagement with the free end of the treadle. tlt will thus be seen that the rod 29 is normally supported in yieldable contact with the log or other work, so that when the treadle 1l is depressed the active end of the rod will be drawn downwardly into engagement with the log, and thus prevent the latter slipping during ythe sawing operation.

It will of course be understood that the bill of the log-enga ing hook in either form of the device may e so proportioned as to embrace the top of the log or to impale the latter, according to the size and shape of the work bein operated upon. It will also be understood that by adjusting the auxiliary support 9 longitudinally of the cross-beam S short sections of logs may be conveniently operated upon without danger of the log tilting, so that the entire log may be conveniently cut or severed into predetermined lengths.

I claim- 1. The combination with a sawbucl, of a treadle, a pivoted work-engaging member carried by the treadle and movable to operative position when the treadle is depressed, means carried by the treadle and engaging the pivoted end of the work-engaging member for actuating said member to grip the work, and means for moving the member to inoperative position when the treadle is released.
